Abstract

The aim of this study was to remove Ra-226 from the contaminated soil samples which collected from one of oil company located at western desert of Egypt. Five soil samples (S-1, S-2, S-3,S-4,S-5) were collected from the bottom of evaporation pond from different positions of dry evaporation pond inside the oil company. The activity concentration of Ra-226 measured by using the Hyper Pure Germanium detector (HPGe) connected to MCA . Electrodeposition technique was used to produce in situ metallic coatings by the action of an electric current on a conductive material immersed in a solution containing a salt of the metal to be deposited. Chemical agents added to the solution to increase the efficiency of contaminant removal nitric acid HNO₃was added to improve the solubility of Ra-226. Three different electrods made from stainless steel, aluminum and cupper poles were used in this study. The data obtained showed that the highest removal percentage of the Ra-226 found to be 73% when the aluminum pole was used. Therefore, from the obtained data, it is clear that the electrodeposition technique using aluminum poles for removal of Ra-226 can be used for remediation or treatment contaminated soil produced from oil industry.
